ALBERT HALL, OF RICHMOND, INDIANA.

ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 321,290, dated June 30, 1885.

Application filed January 8, 1885.

T0 aZZ whom it may concern:

Be it known that I, ALBERT HALL, a citizen of the United States, and aresident of Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Roller-Skates, of which the following is a specification.

My invention relates to roller'skates, and refers to the means for connecting the rollers and their axle to the springframe; second, to means for hinging the spring-frame to the bracket; and, third, to means for adjusting or taking up the spring tension, all of which will be fully set forth in the description of the accompanying drawings, in which Figure 1 is a vertical cross-section at right angles to the axes of the rollers. Fig. 2 is a section on line :0 :0, Fig. 1. Fig. 3 is a bottom plan view of the bracket. Fig. 4 is-a perspective view of the spring'frame.

A represents the rollers; B,the axle; G, the spring-frame,which is provided with ears D, in which the axle B is rigidly secured.

E represents a sleeve or journal-bearing, which is rigidly secured to the inside of roller A in any desired manner. 1 represents a circular flange turned on the inner end of the sleeve E.

2 represents a lug projecting from ear D over the flange 1 down upon the cylinder of the sleeve. These lugs 2 are preferably segments of circles, and they serve to rigidly secure the rollers A in position on their axle in the following manner: The bushings or sleeves E are pressed or secured to the rollers A, then placed in position with the flanges 1 within the lugs 2. Then the shaft B is driven through the sleeve or bushing E and through the ears I), and the parts are rigidly secured together. This is an improvement over the spring-pin or screw method of holding the rollers A upon the axle.

The spring-frame O is cast with a hollow or opening, F, in which is placed the ordinary compression rubber spring, H.

I represents a boss, cast on and with the frame F. It is screw'threaded, to receive a tempenscrew, G.

K represents an enlarged head of the screw (Mod cl.)

upon the point oftemper-screw G, and turning with it.

L represents a metal plate resting upon the head K of the temper-screw, having its inner end, 2', turned over, to prevent its being displaced.

M represents a bracket, which is provided with ears m,for securing the same to the skateboard by means of screws or otherwise, N N representing downwardly-projecting lugs which are pierced with holes to receive the pivot O, which pivot passes through holes 1? in the frame 0, so as to pivot the bracket M to the frame 0.

Q represents a spring-seat,which is formed by the bottom of the casting of bracket M suitably reduced to lie between the ears 1" of frame 0. The outer edges,s, are beveled off a sufficient amount to strike against the sides 0 of the frame G,to prevent the skate-board from being canted or tipped too far laterally.

The compressionspring H rests upon the plate L, which in turn rests upon head K of temper-screw G. WVhen temperscrew G is turned down,plateL transmits pressure equally to the bottom surface of the rubber spring H, compressing it within the box F, so as to regulate the strain or tension upon the bracket M, which tends to hold the sole of the skate in horizontal planes. The rubber can be easily inserted and removed through the opening F, and a wrench applied to the head of temper-screw G will readily adjust the spring without taking the skate 0d the foot of the wearer.

Having described my invention, what I claim as new 1s 1. The combination of the axle B,and the ears D, provided with lugs 2, engaging with the sleeve E, which is rigidly secured to the hub of the roller A, whereby the parts are held in fixed relation, substantially as specified.

2. The combination of the axle B, the frame 0, having ears 9', the brackets M, provided with lugs N, the pivot O, passing through the ears '2- and lugs N, and the spring H, seated between frame 0 and bracket M, substantially as described.

3. The combination of axle B, firame C, hav

to prevent displacement, and headed temper 1o screw G K, substantially as described.

In testimony whereof I have hereunto set my hand.

ALBERT H ALL.
